Ken, following today's flight, I know I will need to add more but not sure of how much. I will measure the thrust angle and double it. From there, I want to see what happens. I now have the engine underproped so if it pulls to the right slightly, it may be ok until I get a new propeller. I am using a 22x6-10 and will be going to a 24x8

Geistware, I realize that you don't like to fool with the engine, I don't either, but the place to start is with about 2 degrees of right thrust. Of course the rear of the engine will need to be moved left to make the prop come out in the right place. Yes, it's a lot of trouble but it has to be done if you want your plane to fly right.
